# 安全员鸣题库 vs 安全员题库

安全员鸣题库 and 安全员题库 are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. 安全员鸣题库 sells 4 one-off in-app purchases and 安全员题库 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
